Royal icing, with its smooth, matte finish and ability to hold intricate designs, is the gold standard for decorating cookies, cakes, and gingerbread houses. A crucial ingredient in achieving this perfect consistency is meringue powder, but what happens when you run out or are looking for an alternative? Don’t despair! There are several excellent substitutes that can deliver equally stunning results. This guide will explore these alternatives in detail, helping you choose the best option for your needs and preferences.
Understanding Meringue Powder’s Role in Royal Icing
Before diving into the substitutes, it’s important to understand why meringue powder is so vital to royal icing. Meringue powder primarily functions as a stabilizer and emulsifier. It provides several key benefits:
- Structure and Stability: Meringue powder adds structure to the icing, allowing it to hold its shape and prevent it from spreading too thin. This is especially important for creating detailed decorations.
- Smooth Texture: It contributes to the smooth, creamy texture that is characteristic of well-made royal icing.
- Hardening: Meringue powder helps the icing to harden properly, creating a durable and long-lasting finish.
- Safety: It eliminates the risk associated with using raw egg whites, making it a safer option, especially for those concerned about salmonella.
Understanding these functions will help you evaluate the effectiveness of different substitutes.
The Best Meringue Powder Alternatives
Fortunately, several ingredients can be used in place of meringue powder, each with its own unique characteristics and advantages. Let’s explore some of the most popular and effective alternatives.
Fresh Egg Whites: The Traditional Approach
The most classic alternative to meringue powder is fresh egg whites. In fact, traditionally, royal icing was always made with raw egg whites.
Using egg whites provides excellent structure and allows the icing to harden beautifully. However, it’s crucial to be aware of the potential risks associated with consuming raw eggs.
Considerations for Using Fresh Egg Whites
- Salmonella Risk: The biggest concern is the risk of salmonella contamination. To minimize this risk, use pasteurized egg whites.
- Proper Handling: Ensure the eggs are fresh and properly refrigerated. Separate the whites carefully, avoiding any yolk contamination, as even a small amount of yolk can interfere with the icing’s ability to stiffen.
- Recipe Adjustments: When substituting egg whites, adjust the liquid content of your recipe accordingly. Egg whites contain water, so you may need to reduce the amount of liquid added.
How to Substitute Fresh Egg Whites
A general guideline is to use one large egg white for every two teaspoons of meringue powder called for in the recipe. Remember to adjust the liquid content as needed.
Pasteurized Egg Whites: A Safer Option
Pasteurized egg whites offer a safer alternative to fresh egg whites. The pasteurization process heats the egg whites to a temperature that kills harmful bacteria like salmonella, without significantly altering their properties.
Benefits of Pasteurized Egg Whites
- Reduced Salmonella Risk: The primary advantage is the significantly reduced risk of salmonella contamination.
- Convenience: Pasteurized egg whites are readily available in cartons at most grocery stores, making them a convenient option.
- Consistent Results: They provide more consistent results than fresh egg whites, as they are standardized for protein content.
Using Pasteurized Egg Whites Effectively
Follow the same substitution guidelines as for fresh egg whites, using one large egg white for every two teaspoons of meringue powder. Monitor the consistency of the icing and adjust the liquid as necessary.
Egg White Powder: Shelf-Stable and Convenient
Egg white powder is another excellent alternative. It’s made by dehydrating egg whites, resulting in a shelf-stable powder that can be easily reconstituted with water.
Advantages of Egg White Powder
- Shelf-Stable: Egg white powder has a long shelf life, making it a convenient option to keep on hand.
- Reduced Salmonella Risk: The dehydration process eliminates the risk of salmonella contamination.
- Easy to Use: Simply rehydrate the powder with water to create a liquid egg white substitute.
Substitution Tips for Egg White Powder
Follow the package instructions for rehydrating the egg white powder. Typically, you’ll mix the powder with water to create a liquid egg white equivalent. Use this rehydrated mixture in place of the meringue powder, adjusting the liquid content of the recipe as needed.
Cream of Tartar: Enhancing Stability
While not a direct substitute, cream of tartar can be used in conjunction with egg whites (fresh, pasteurized, or rehydrated from powder) to enhance their stability and create a more voluminous icing.
How Cream of Tartar Works
Cream of tartar is an acid that helps to stabilize egg whites when they are whipped. It prevents the proteins from collapsing, resulting in a more stable and voluminous meringue.
Using Cream of Tartar in Royal Icing
Add a pinch (about 1/8 teaspoon per egg white) of cream of tartar to the egg whites before whipping them. This will help to create a more stable and glossy icing.
Gelatin: An Unexpected Alternative
Gelatin might seem like an unusual choice, but it can effectively stabilize royal icing and help it to harden properly. It’s especially useful for creating very stiff icing for intricate designs.
How Gelatin Works in Royal Icing
Gelatin is a protein that forms a gel when dissolved in water. This gel structure helps to bind the ingredients in the icing together and provides added stability.
Using Gelatin as a Substitute
- Bloom the Gelatin: Dissolve a small amount of unflavored gelatin in cold water according to the package directions.
- Melt the Gelatin: Gently heat the gelatin mixture until it is completely dissolved. Be careful not to boil it.
- Incorporate into Icing: Gradually add the melted gelatin mixture to the royal icing, mixing well to ensure it is evenly distributed.
Start with a small amount of gelatin, as too much can make the icing too stiff. A good starting point is about 1/2 teaspoon of gelatin powder bloomed in 1 tablespoon of cold water for a standard batch of royal icing.
Aquafaba: A Vegan Option
For those seeking a vegan alternative, aquafaba – the liquid from canned chickpeas – is a surprisingly effective substitute.
The Magic of Aquafaba
Aquafaba contains proteins and starches that mimic the properties of egg whites, allowing it to be whipped into a meringue-like foam.
Using Aquafaba in Royal Icing
- Drain and Reserve: Drain the liquid from a can of chickpeas, reserving the aquafaba.
- Whip the Aquafaba: Whip the aquafaba with an electric mixer until it forms stiff peaks. This may take a bit longer than whipping egg whites.
- Gradually Add Sugar: Gradually add powdered sugar to the whipped aquafaba, mixing until the icing reaches the desired consistency.
Aquafaba can sometimes have a slight chickpea flavor, but this can be masked by adding flavor extracts like vanilla or almond.
Adjusting Your Recipe and Technique
Regardless of the substitute you choose, it’s important to adjust your recipe and technique to achieve the best results.
Liquid Consistency
Pay close attention to the consistency of the icing. Different substitutes will affect the liquid content, so you may need to add more or less liquid (usually water) to reach the desired consistency.
Mixing Time
Mixing time can also vary depending on the substitute. Be patient and mix the icing until it is smooth and glossy. Avoid overmixing, as this can cause the icing to become too thin.
Humidity
Humidity can affect the drying time of royal icing. In humid conditions, the icing may take longer to dry. To speed up the drying process, you can use a dehumidifier or place the decorated items in a cool, dry place.
Troubleshooting Common Problems
Even with the best ingredients and techniques, you may encounter some common problems when making royal icing. Here are some tips for troubleshooting:
Icing is Too Thin
If the icing is too thin, gradually add more powdered sugar until it reaches the desired consistency. Add the sugar in small increments, mixing well after each addition to avoid making the icing too thick.
Icing is Too Thick
If the icing is too thick, add a small amount of water, one teaspoon at a time, until it reaches the desired consistency. Mix well after each addition to ensure the water is evenly distributed.
Icing is Cracking
Cracking can occur if the icing dries too quickly or if it is not properly hydrated. To prevent cracking, keep the decorated items covered while they are drying. You can also add a small amount of glycerin to the icing to help it retain moisture.
Icing is Not Hardening
If the icing is not hardening properly, it may be due to high humidity or insufficient meringue powder (or its substitute). Ensure the decorated items are in a cool, dry place and consider adding a small amount of cornstarch to the icing to help it dry faster.
Choosing the Right Substitute for You
Ultimately, the best meringue powder substitute for you will depend on your individual needs and preferences.

Can I use egg whites directly in royal icing instead of meringue powder?
Yes, you can use fresh egg whites in royal icing as a substitute for meringue powder. It is a classic method that predates the widespread availability of meringue powder. When using fresh egg whites, be extremely careful to ensure the eggs are pasteurized or from a trusted source to minimize the risk of salmonella.
To use fresh egg whites, replace the meringue powder with the equivalent volume of egg white (usually about 1 large egg white per 2-4 tablespoons of meringue powder). Note that royal icing made with fresh egg whites may not be as stable or have as long of a shelf life as royal icing made with meringue powder. It is best used immediately or within a few days, stored properly in the refrigerator.
What is the best liquid egg white product to use as a meringue powder substitute?
Pasteurized liquid egg whites are a convenient and safer alternative to fresh egg whites. They eliminate the concern of salmonella and provide consistent results. Look for pure pasteurized egg whites without any added ingredients such as stabilizers or preservatives, as these can affect the consistency and drying time of the royal icing.
When substituting liquid egg whites for meringue powder, use approximately 2 tablespoons of liquid egg white for every tablespoon of meringue powder called for in your recipe. Be sure to adjust the amount of liquid in the recipe accordingly, often by reducing the water slightly. The icing may require a longer drying time compared to icing made with meringue powder.
How does aquafaba work as a substitute for meringue powder in royal icing?
Aquafaba, the liquid from canned chickpeas, is a vegan-friendly substitute for meringue powder. Its protein and starch content allow it to whip up and create a similar structure as egg whites, providing stability to royal icing. Ensure you’re using unsalted aquafaba to avoid altering the icing’s flavor profile.
To use aquafaba, whip it until stiff peaks form before adding the powdered sugar and other ingredients. You’ll generally use about 2 tablespoons of aquafaba to replace 1 tablespoon of meringue powder. Aquafaba-based royal icing might have a slightly different texture and may take longer to dry than traditional royal icing.
Will using cream of tartar achieve the same results as meringue powder?
Cream of tartar is not a direct substitute for meringue powder, but it can improve the stability and texture of royal icing made with other substitutes, such as egg whites or aquafaba. It acts as a stabilizer, helping the icing hold its shape and prevent it from becoming grainy. It does not, however, contribute to the volume or structure in the same way that meringue powder does.
To incorporate cream of tartar, add a pinch (about 1/8 teaspoon) to your royal icing recipe, regardless of whether you are using fresh egg whites, liquid egg whites, or aquafaba as a meringue powder alternative. The cream of tartar will enhance the stability of your icing, aiding in sharper lines and preventing the icing from separating.
Can cornstarch be used as a meringue powder substitute to stiffen royal icing?
Cornstarch is not a direct replacement for meringue powder because it lacks the protein necessary for creating a stable, meringue-like structure. However, it can be used in small amounts to help stiffen royal icing and prevent it from becoming too runny. It’s more of an additive than a substitute.
When incorporating cornstarch, add it gradually, starting with about 1/2 teaspoon per batch of royal icing. Too much cornstarch can make the icing brittle and prone to cracking. It’s best used in conjunction with another meringue powder substitute like liquid egg whites or aquafaba to provide added structure.
What impact does substituting for meringue powder have on drying time?
Substituting meringue powder can significantly impact the drying time of royal icing. Fresh egg whites and aquafaba, for example, typically result in longer drying times compared to royal icing made with meringue powder. This is because they contain more moisture and less of the concentrated protein found in meringue powder.
To mitigate longer drying times, ensure your royal icing is mixed to the correct consistency and that you are decorating in a dry, well-ventilated environment. You can also use a dehydrator or fan to gently circulate air around the decorated cookies, which will help to speed up the drying process. Remember, fully dried icing is crucial for proper storage and prevents smudging.
Are there any flavors or textures I should expect differently when replacing meringue powder?
When substituting meringue powder in royal icing, expect subtle differences in both flavor and texture. Fresh egg whites might impart a slight eggy taste, while aquafaba can have a faint bean-like flavor that is generally masked by the sweetness of the icing. Meringue powder has a neutral flavor, so any substitution will introduce a slight flavor variation.
Texture-wise, royal icing made with fresh egg whites tends to be slightly softer than that made with meringue powder. Aquafaba-based icing may be a little less glossy and more prone to air bubbles. These textural differences are generally minor but can impact the final appearance and handling of your decorated treats. Experimentation is key to finding the substitution that works best for your particular recipe and preferences.
